Although different types of multimeters can have more or fewer functions, you can safely assume that your multimeter is equipped to test a wire for power. A typical multimeter can measure voltages within the range of 200 mv to 600 v ac or dc. Touch both red and black test leads to both wires or fuse ends.

With the tester’s lights (if any are on) showing the situation about the plug’s wiring, make note of any wiring anomaly indicated. Three major wires (positive, neutral, and ground) run through most electrical cords. Be certain to touch around the cord. Using the device is done through putting the two probes which are on the device onto a red and black wire.
